When using Streams or Q&A you may need to call to attention a team member. To do this, type the @ symbol followed by that person’s name.
After you have typed a few letters some suggestions will come up.
Once you have selected the person from the list and sent your message, that person will be sent a direct message alerting them that they have been mentioned in a stream.
You can then click on the link and it will take you to the exact place where you have been mentioned.
